They can help to reduce energy bills

While the upfront cost of a heat pump is significant, typically starting at around £6,000, the annual savings can be considerable, particularly if you’re changing from old-fashioned systems. An air source heat pump could save up to £1,330 per year compared to old electric storage heaters, or up to £1,410 per year compared to an old gas boiler⁵.

You could also get some financial support for installing a heat pump in your home.  

• Up until March 2022 you can apply for financial support through the Domestic Renewable Heat Incentive (RHI), a government scheme to encourage investment in renewable energy. While amounts vary according to your home type and existing heating system, it’s possible to claim as much as £11,000 back in quarterly payments over seven years.
• From April 2022, the Government is offering grants of £5,000 towards to upfront cost of having a heat pump installed in your home.

They have a longer lifespan than a traditional gas boiler

Typically, a traditional gas boiler lasts up to around 15 years and will become less efficient as time goes on and will have to work harder to heat your home. A well-maintained air source heat pump could last up to 20 years.
